Answer: b = -20
Step-by-step explanation: I have difficulty reading the table of values of (x,y). I picked just the first (10, -120) to calculate b.
y = -10x + b
-120 = -10(10) + b
b = -20
That should work for all the points:
(20, -220) : -220 = -10(20)-20 - Yes, etc.
But the values towards the end of the table don't makes sense/don't work. (0, -2)????

PLEASE PLEASE PLEASE HELP TRANSLATING SENTENCES INTO EQUATIONS
Answer:
5×(w + 7) = 4
Step-by-step explanation:
w is the unknown number.
5 times something means multiply something 5 times.
a sum means adding things
so, the sum of a number and 7 is
w + 7
5 times that sum is then
5×(w + 7)
and that while thing is (equals) 4
5×(w + 7) = 4
by the way, solving that means
5w + 35 = 4
5w = -31
w = -31/5
Answer:
5(w + 7) = 4
Step-by-step explanation:
Do one part of the sentence at a time until you write the entire sentence as an equation.
"Five times the sum of a number and 7 is 4."
The problem tells us to use w for the number, so we write w below.
w
"Five times the sum of a number and 7 is 4."
Now we move on to the part dealing with the sum of the number and 7. A sum is an addition, so we add 7 to the number w.
w + 7
"Five times the sum of a number and 7 is 4."
Now we take care of the part dealing with product of 5 and the sum.
5(w + 7)
"Five times the sum of a number and 7 is 4."
The last part is dealing with the part "is 4". The word "is" very often means "equals", so the entire expression we wrote is equal to 4.
5(w + 7) = 4
Answer: 5(w + 7) = 4

The answer is a complex number because complex numbers are closed under multiplication.
The answer is not a complex number because it cannot be written in the form a +bi.
The answer is a complex number because it can be written in the form a + bi.
Answer: B and D
Step-by-step explanation:
Answer:
A number that can be expressed in the form of [tex]\[(a+bi)\][/tex] is called the complex number , where [tex]\[a,b\][/tex] are real numbers and [tex]\[i\][/tex] is imaginary numbers.
Step-by-step explanation:
• Given problem [tex]\[(-2+i)(3-6t)\][/tex] we have to find that the given number is complex or not . In order to do so we have to expressed the number in form of [tex]\[(a+bi)\][/tex] .
• If we got this form then number is complex number otherwise it is real number.
[tex]& (-2+i)(3-6t) \\ & -6+3i+12t-6ti \\ & (-6+12t)+i(3-6t) \\[/tex]
• We got the [tex]\[(a+bi)\][/tex] form .Therefore number is complex number.
• Hence option four is correct.

The denominator of a rational number is greater than its numerator by 7. If the numerator is increased by 6 and the denominator is decreased by 5, the new rational number obtained is 3/2. Find the original rational number.

Step-by-step explanation:

Answer:
Original Rational number is = 6/13Step-by-step explanation:
Let Numerator be : x
Denominator be : x + 7
Now,
Numerator is increased by 6Denominator is decreased by 5the new rational number obtained is 3/2Numerator = x + 6
Denominator = ( x + 7) - 5
According to the question,
[tex] \displaystyle \: \sf \dashrightarrow \: \frac{x + 6}{(x + 7) \: - 5} = \: \frac{3}{2} [/tex]

A quart floor has a side length of 7x^5y^6 units. A square tile has a side length of x^2y units. How many tiles will it take to take to cover the floor?
About 49 tiles will be needed to cover the floor
A square is a shape having equal sides. The area of a square is expressed as:
A = L²
L is the side length of a square.
If a square tile has a side length of x²y units, the area of the square tile will be:
A = (x²y)²
As = x⁴y² units²
Similarly, if a quart floor has a side length of 7x⁵y⁶ units. The area of the quart floor will be expressed as:
Aq = (7x⁵y⁶)²
Aq = 49x¹⁰y¹²
Divide both areas to get the number of tiles that will cover the floor
Number of tiles = 49x¹⁰y¹²/x⁴y²
Number of tiles = 49x⁶y¹⁰
This shows that about 49 tiles will be needed to cover the floor.

A regular square-based pyramid has a surface area of 33 m2. If its triangular faces have an area of 6 m2, what is the length of the base of the pyramid?
Answer:
First we can do 33 time 6
Step-by-step explanation:
The length of the base of the pyramid is 3 meters.
What is a square pyramid?A pyramid is a polyhedron that has a base and 3 or greater triangular faces that meet at a point above the base. A square pyramid is a pyramid with a square base, four triangular sides, five vertices, and eight edges.
For the given situation,
The surface area of the pyramid = 33 m^2
Area of triangular faces = 6 m^2
Let the base of the pyramid be b and the height be h.
The formula of area of triangle is
[tex]A = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6 = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6(2) = (b)(h)[/tex]
⇒ [tex]12 = (b)(h)[/tex]
The formula of surface area of square pyramid is
[tex]SA = b^{2}+2bh[/tex]
⇒ [tex]33=b^{2} +2(12)[/tex]
⇒ [tex]33-24=b^{2}[/tex]
⇒ [tex]b=\sqrt{9}[/tex]
⇒ [tex]b=3[/tex]
Hence we can conclude that the length of the base of the pyramid is 3 meters.

For which value of x is the figure a rectangle?
Answer:
x = 11
Step-by-step explanation:
The vertices of a rectangle are right angles (90° ) , then

8x + 2 = 90 ( subtract 2 from both sides )
8x = 88 ( divide both sides by 8 )
